Since 2019, due to the extreme suppression, Huawei's mobile phone sales have plummeted, completely reduced to a marginalized niche brand. However, the amazing thing is that even if the sales of Huawei mobile phones have fallen sharply, its reputation and popularity have not dropped much compared with the heyday. Such a good situation is due to Huawei's insistence on self-research in various software and hardware technologies of mobile phones
So now Huawei's mobile phone will cause heated discussion among netizens. And just today, a latest patent for Huawei mobile phones was exposed, called the display unlocking method and its device patent, the function is to prevent users from unlocking the phone through the face when coerced

In 2017, Apple released the iPhone X for the first time to introduce 3D structured light
But it still belongs to a kind of face recognition, Android phone face recognition is mostly 2D plane scanning, and the iPhone's 3D structured light is a 3D full-angle scanning, which is more secure. Whether it is fingerprint recognition or face recognition, it is based on unique biometrics
Its security has been affirmed by all users around the world. However, there are some special cases that are not safe, that is, the case of kidnapping or coercion, and Huawei's patent solves this problem very well, the method is to obtain the user's current pupil parameters and the reflected light intensity of the face through the camera module when the display is in the lock screen state and the bright screen state
If the current pupil parameter is greater than the pupil parameter unlocked by the face, the user's current micro-expression is obtained; If it is determined that the user is currently in a state of coercion based on micro-expressions, a preset unlock interface is displayed, which includes password, fingerprint, iris, voice and sound waves at least one
Huawei said the patent prevents users from unlocking the display of electronic devices through their faces when coerced. In response to Huawei's new black technology, many netizens joked that Apple should cooperate with Huawei in time to add this function on the iPhone.
